KILLER SOUND

摘要

Ocean research, navigation, seafloor mapping, object-tracking (sonar, for example)-they all rely on sound, which is still the best way to transmit information through water. So we wanted to build the ultimate hydrophone, one that could listen to the quietest sounds and the loudest sounds and could work anywhere, even six miles underwater, where the atmo-spheric pressure is 1,000 times as much as it is up top. Whale ears were our inspiration.
